The method relies on the stereological principle that overlaying a grid of points onto a 2D section of a material provides an unbiased estimate of the 3D volume fraction.

• E562-19 applies to preparation of cohesive and cohesionless soils prior to PSD tests (sieve and sedimentation) and other index tests that require a representative mass of material.
• It addresses coarse- and fine-grained soils, wet and dry conditions, and samples from field collections or bulk lab stocks.
• It is intended for geotechnical, civil, and environmental laboratories performing standard soil characterization.

To achieve statistical significance, ASTM E562-19 requires counting a minimum total number of points (typically 400 to 1,000) across at least five or more random fields. The standard also provides guidelines for calculating 95% confidence intervals using the binomial distribution, ensuring the estimate's precision. Subject: ASTM E562-19 PDF The method relies on
